Why We Grow It

We grow Kobus Magnolia for its exceptional cold hardiness, early-season beauty, and dependable flowering in northern climates. Its clean branching and fragrant, star-like flowers make it a standout feature tree, while its resilience and low-maintenance nature fit perfectly into homesteads, ornamental plantings, and food forest edges. For growers seeking a reliable magnolia that can handle real winters, Kobus is one of the best options available.

How the Plant Grows

Kobus Magnolia begins with upright growth that gradually spreads into a rounded, pyramidal form as it matures. In early spring, it produces abundant white, star-shaped blooms along bare branches, often before most other trees have leafed out. Growth is moderate, with strong branch structure and good wind tolerance. Leaves emerge after flowering and turn yellow in autumn. This species thrives in well-drained soils and adapts well to northern climates where other magnolias may struggle.
